Compressed BIOS package for the Acer Aspire A515-51, specific configuration 51UX. NCL is not explained in the name and is left unexpanded here. The 5.01 MB archive may hold a vendor update or a raw dump, so unpack it and check the file size against the SPI chip before use. On this generation the flash is typically 8 or 16 MB, so a mismatched image will not program correctly. Always read and keep the original firmware before writing anything.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @abgm_manutencao_bios. Enginerys does not host this file.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
